Its high record of pollution is due to indiscriminate discharge of huge quantities of pollutants generated by industries, mining and mineral processing industries which are con­centrated on both sides or in the proximity of the river. Microorganisms play important role in the overall process which consists of several reactions. This project report will help you to learn about: 1. 4.1: Unlimited discharge of untreated sewage into a water body hastens the above process greatly. Release minerals (e.g. 3. Feb 12, 2015 - Explore Paperfloralfantasies's board "pollution posters" on Pinterest. According to the World Economic Forum, rising water pollution is the foremost global risk in terms of its potentially devastating impact on society. Organophosphorus group e.g. (f) Fluoride containing pollutants cause fluorosis i. e. neuromuscular, respiratory gastro intestinal and dental problems. 8-9; B.O.D. Impurities get added to it as it percolates beneath the surface of the earth and also when it is used for human activities. These wastes may accumulate in the bodies of aquatic animals like fishes causing harm to them as well as animals which eat them. See more ideas about water pollution quotes, pollution, water pollution. The number of microbes (Escherichia coli) also increases tremendously which con­sumes most of the oxygen. The water pollution caused by diffused sources like agriculture can be controlled by changing the cropping patterns, tillage particles and advanced farm management practices which do not contaminate the water bodies. This huge sediment load is due to (a) high erosion rate of Hima­layan rocks (birthplace of Ganga), (b) large size of drainage basin with steep angle of eleva­tion in the Himalayan region, (c) numerous tributaries transporting soil to the main stream, (d) dense population in most part of the basin with their intense agricultural practices. Water tastes bitter when contaminated with alkaline impurities and salty when the impurities are metallic salts. Sewage consists of the excreta (faeces and nitrogenous wastes) of animals. Detrimental effect on the commercial and sport-fishing industry due to changes in the species of fish caused due to low dis­solved oxygen. The number of bacteria (E. coli) in unit volume of water (called E. coli index) is also taken as a para­meter of water pollution. in the long run and ends up in a dead pool of water. DDT; carbamate group e.g. Cadmium poisoning is, called itai-itai (“ouch-ouch”) in Japan because it is a painful disease that can be fatal. (a) Bathing and washing of clothes in rivers and streams. which kill aquatic organisms and may reach human body through contaminated food (i.e. The concentration of these toxic pollutants in barrage water are above the permissible limits for surface water. Most of the earth’s surfaces water is in the oceans, which contains about 35 parts per thou­sand of dissolved salt of the remainder, most of fresh water with salt content of 0.2% of found either in lakes and ponds (still water) or in rivers and streams (running water). The incidences of liver diseases such as hepatitis, jaundice, dysentery etc. After using the water, manufacturing plants, industries, residential, and commercial establishments discharge wastewater which is contaminated by many pollutants. The word eutrophication stems from two Greek words: eu, meaning ‘good’ or ‘well’ and trophic meaning ‘food’. (iii) Sewage and run off from agricultural lands provide plant nutrients in natural settings, in the natural biological process called eutrophication (Greek word: well nourished). 8-9; B .O.D. Growth of algae, micro-organisms, hydrogen sulphide and ammonia give an obnoxious odour to water making if unfit for use. Each year, approximately 70,000 kinds of organic chemicals are placed on the market that ultimately make their way through environment to the water. Common Sources 6. Different type of water uses require different levels of water purity with the highest level of purity being required for drinking water. The hyppliminitic zone represents a condition where the biological decomposition of organic matter consumes all dissolved O2, which cannot be made up since these layers are stagnant and cut off from the atmosphere. (iii) Water possesses the highest heat of fusion and heat of evaporation, collectively known as latent heat, of all known substances that are liquid at ordinary temperature. fishes etc.). However, it was known that arsenical pesticides can persist in soil for up to 40 years and damage crops. 2. iv. Water-borne diseases may occur and it may assume epidemic state. The total number of grab samples should satisfy the requirements of the sampling programme. water is alkaline) the following defects will result-incrustation, sedi­ment deposits, difficulty in chlorination and physiological effects on human bodies. Sewage consists of nitrates, phosphates, sodium, potassium, calcium etc. Oil pollution of the seas has increased over the years due to the increased use of oil- based technology. Caustic soda and chlorine factories release heavy metals such as cadmium, chromium, copper, lead, nickel, zinc and mercury. Inorganic nutri­ents (such as phosphorus) stimulate the production of organic detritus, adding to the BOD. It can become highly concentrated in the bodies of fishes. These influence the fertility or productivity of soil in several ways: i. Effects 11. Besides mining, transport and trade, there are some 50 large, 100 medium and 200 small industries units extending from Giddi in Hibar to Durgapur in W.B. See more ideas about pollution, ocean pollution, water pollution. All these materials undergo degradation by bacterial activity in the presence of D.O., the net result being the de-oxygenation process and quick depletion of D.O. Non-point source of load, such as agri­cultural runoff, can be reduced through land management techniques that pre­vent soil erosion and avoid excessive use of fertilisers. This accelerated process is sometime referred to as cultural eutrophication. Coal mines, especially those which have been abandoned, discharge substantial quantities of H2SO4 and also Fe (OH)3, into local streams through sewage. (b) Discharging untreated or treated domestic, commercial and industrial sewage in water bodies. 10. These nutrients make the water bodies highly productive or eutrophic and the phenomena is called eutrophication. Affects recreation and tourism due to excessive growth of algae and other aquatic plants, making the water and beaches unfit for recreation purposes. Waste containing toxic substances damage biological activity and kill useful organisms. (d) Treated water can be reused for cooling processes in thermal plants. The significance of a chemical analysis to a large extent depends on the sampling programme. Decomposition of blooms also lead to further oxygen-depletion in water. Examples 13. It is rich in organic matter and nitrogen compounds. Water Pollution Control and Management: Clean water is essential for healthy environment to support life systems on this planet. In the sixteenth century the Chinese are used arsenic sulphide as an insecticide. Thiobacillus ferroxidans. Decompose toxic substances to harmless forms. level of the aquatic system making it incapable of supporting life. Further­more, in the process of water treatment, chlorination enhances toxicity of water by forma­tion of toxic chloramines and chlorophenols through reactions with NH3 and phenol respec­tively. It may be stated, in general, that it is more meaningful to analyze a large number of separate samples taken at different times and different locations than to compile and analyse a single representative sample. km. The Hooghly river near Calcutta is contaminated with waste effluents from about 150 industries (including 87 jute mills, 12 textile mills, 7 tanneies, 5 paper mills and 4 distilleries) as well as domestic sewage from 360 out falls on both sides of the river. The coak works and plastic wastes have much phenolic compounds. Thousands of new, high Algal bloom (often filamentous algae) floating on water forms a scum or blanket and are generally not utilised by zooplankton. The high intensity of cultivation in the rural sectors, high population density and high concentration of factories in towns and cities account for generation of huge amounts of organic and inorganic pollutants in the basin most of which finally find their way into the main stream. The sources of oil pollution are oil spill from cargo oil tankers on the seas, losses during off-shore exploration and production of oil, and leakage from oil pipe­lines crossing waterways and reservoirs. The water borne diseases are typhoid and paratyphoid fevers, dysentery and cholera, polio, and infections hepatitis. Sewage increases the biological productivity and interferes with many uses of the water body. If used as a fertilizer in moderate concentrations, animal excreta (manure) can enrich the soil. (c) Domestic, commercial and industrial effluents (petroleum refineries, paper mills, distilleries, tanneries, slaughter houses) contaminate the water with organic pollut­ants. Water pollutants can be classified into the following categories: (a) Suspended matter (Solids) comprises of silt, sand, mineral codes. Stimulate bacterial multiplication which would reduce the amount of nutrients solubilized in water and check profuse algal growth. For analysis of natural and waste water, two principal types of sampling procedures are employed: 1. In this case, the pollutants scattered on the ground ultimately reach the water sources and cause water pollution, for i-instance, agriculture (pesticides, fertilisers), mining, construction etc. Project Report, Environment, Pollutions, Water Pollution, Project Report on Water Pollution, Terms of Service Privacy Policy Contact Us. People in the industrial belt are constantly exposed to health hazards due to synergic effect of water pollution and industrial air pollution. are introduced into the natural environment. As a matter of fact, tem­perature, pH and dissolved gases (D.O.) Hardness is the property of water on account of which it consumes soap without form­ing lather freely. Major Sources 5. But soil is greatly localized. endobj A representative single sample is taken from a number of different locations over a long period of time. 4. In some cases these metals concentrate through the food chain to levels that result in heavy metal poisoning. Microbial activity reduces phenol or C.O.D. This area is known as the “River of India”. Fine particles of dust, clay, soil, ores are other pollutants of water. << /Type /Page /Parent 3 0 R /Resources 6 0 R /Contents 4 0 R /MediaBox [0 0 540 720] Water fit for drinking should have a BOD value of less than 1 ppm. 37 Water Pollution Art for Kids 2020 In 2020. At pH 3.5-4.5 the reaction may be catalyzed by a variety of bacterium, Metallogenium. Radioisotopes are said to cause cancer, malformation of body at birth, organ abnormalities etc. (80-350 mg/I), sulphide (1.5-15 ppm), Hg (0.01-0.05 ppm) which are deposited in the river bed. level of water, killing fish and other aquatic organisms. Oil from spills and washing of automobiles sometimes pollutes our water. If pH is more than 7 (i.e. Introduction to Water Pollution 2. km in the industrial belts of Hooghly and 24 paragraph. Paris green (Copper acetoarsenite) was extensively applied to pools in the tropics for controlling malaria transmitting mosquitoes. (ii) It has a high specific heat and this property of high heat capacity of water is functionally important to aquatic organisms, and. (d) Input from land and atmosphere, e.g. Redox reactions are likely to cause large errors in analysis. (c) Reclaimed waste water can be used for irrigation or municipal purposes. 11. Youth are inheriting a world filled with problems that they did not create. endobj As it is a vital resource essential for sustaining life, contamination of water has immedi­ate as well as far reaching effects on the health and environment of living organisms. The production of synthetic organic chemicals (more than 60 million tonnes each year as in 1980) has multiplied about ten times since 1950. The water bodies rivers, lakes and estuaries are con­tinuously subject to a dynamic state of change with respect to their geological age and geochemical characteristics. This field is for validation purposes and should be left unchanged. The water body, in the process of eutrophication, loses all its D.O. (e) Water borne infectious enteric diseases like typhoid, bacillary dysentery, cholera and amoebic dysentery are the predominant health hazards arising from drinking contaminated water. The level of mercury in freshwater lakes and rivers have been rising in recent years. A project report on water pollution. Turbidity increases and sedimentation makes the requirement of COD high. Indian Iron and Steel Co., Cycle Corporation of India, Carew and Co., Bengal Paper Mill and Durgapur steel plant discharge various types of pollutant (some are non-degradable and persistent) which accumulate in Durgapur barrage water. Classification of Water Pollutants: Water is used for various purposes like bathing, excretion, laundry, food preparation, cleaning of floors and equipment etc. Fresh water is also available in the form of rains, snow, dew etc. The Ganga basin in the home of about 37% of the total population of the country. Surprisingly, the effect of oil on phytoplankton appears to be slight, but oil pose serious threat to marine animals especially fishes and birds. These include fuels, plastics, plasticizers, fibres, elastomers, solvent, detergents, paints, insecticides, food additives and phar­maceuticals. (ii) Water is the carrier of pathogenic microorganism and can cause immense harm to public health. If these substances are present in water in optimum level, they do not cause pollution. See more ideas about pollution, water pollution, water pollution poster. Biological decomposition of organic debris impart a characteristic taste and odour of rotten eggs which is mainly due to hydrogen sulphide. According to Hutchinson (1969), eutrophica­tion is a natural process which literally means “wellnourished or enriched”. Lathering occurs only after all the hardness ions are precipitated by the soap (the water gets ‘softened’ by the soap) and the precipitated (soap and ions) adheres to the surfaces of articles [skin (the precipitate present in the skin pores makes the skin feel rough) tub, sink, clothes, dishes etc.] and a stretch of 2525 km. About 84% of the people live in rural areas while 16% are distributed in 692 cities and towns of the basin. Collection of truly representative sample is as important as sample preservation. This may interrupt or prevent the reproduction of fish by smothering eggs laid on the bottom. km., compared to 200 for the whole of India. At very high level of pollution there is very little dissolved oxygen and the animals present are the chironomid larvae (blood worms) and the oligochaete worm, Tubifex. All are available Introduction Water pollution is a major global concern all over worldwide and the water resource policy keeps the records at all levels. Environment of Aquatic in Water 8. 50 Ways to Save Water Poster Pictures and Slogans Lines for. Multivalent metallic cations, (Calcium, Magnesium, Iron, Manganese, Strontium, Aluminium) in solution contribute to hardness in water. 5 0 obj (b) Thermal discharges waste hot water returned to the original water bodies. The discharge of huge quantities of municipal and domestic wastes and sewage pollute many water bodies. 4-7; B.O.D. Adding large amount of inorganic fertilizers to crop fields result in the nutrient enrichment of streams, rivers and lakes. Pollution Project Objective: Students will create a power point or poster board presentation in groups of 2-3 students which will describe one type of water pollution. Oil pollution reduces light transmission through surface water, and hence, photosynthesis by marine plants, decreases D.O. Nymphs of stone fly and may fly are the first to disappear. Water pollution is a state of deviation from the pure condition, where by its normal function and properties are affected. Various industries require water for cooling. All these metals are capable of binding with enzymes and interfering with normal cell metabolism. infiltration of industrial effluents, municipal sewage etc. Nov 11, 2019 - Explore Santosh Kumar's board "Water pollution poster" on Pinterest. Abundant algal bloom creates unplea­sant taste and odour in water supplies and plugs filters in water treatment plants. Bacteria normally found in the water are able to convert nitrate ions fertilizers and organic wastes to nitrite. (h) Oil pollutants have been known to be responsible for the death of many water birds and fishes. The task of delicately balancing the ratio of available and exploitable water resources and sustaining their quality is most relevant in India where rainfall distribution is uneven and confined to 3-4 months in a year. They are followed by shrimps, water fleas, lee­ches, snails and most of the fishes. But is sewage is allowed to accumulate in lakes and rivers, it can have serious effects on an ecosystem. and respiratory diseases such as bronchitis, bronchial asthma, pulmonary tuberculosis etc. The conventional water treatment methods fail to remove organic matter, phenol and toxic metals so that these find their way into domestic water supply. Water Education Posters from the US Geological Survey: Each poster comes with an educational section describing components of the poster and activities to help children understand the concepts introduced. 5. The water cycle is continually changing from liquid water to water vapor to ice. These conditions are met by collection of samples through a process of random selection. Control of Water Pollution: The following measures can be taken to control water pollution: For minimising thermal pollution, hot water should be cooled before release from factories, and removal of forest canopies and irrigation return flows should be prohibited. This has adverse impact on the health status of the population residing in the estuarine areas. The tannins, humic acid etc. Pesticide is the general term for insecticides, acaricides, rodenticides, molluscides, herbicides, fungicides and similarly active compounds.

The preservation techniques for various parameters are summarized in Table 7. Metal finishing plants release heavy metals and cynides. Changes in faunal composition. Since this project was the biggest part of our final grade for the class, it took Samples may be composited over any time period, such as 4, 8 or 24 hours, depending on the purpose of analysis. 0.25-4.5 ppb). Classification 7. Oil is a major pollutant in the sea. Cesium is known to accumulate in body muscles, Strontium in bones and Iodine in thyroid. ]7n|æ™gÒ%ÇA‘é +V좋.jӦ̓>Ȃš. Thus water quality characterization must take in to account: (a) The distribution dynam­ics of chemicals in the aqueous phase (soluble, colloidal or absorbed or particulate matter); (b) Accumulation and release of chemicals by the aquatic biota; (c) Accumulation and release by bottom deposits; and. Water pollution can be defined as the presence in water, of some foreign Substances or impurities (organic, inorganic, radiological or biological in such quantity so as to constitute a health hazard by lowering the water quality and making it unfit for use. In the early period of human civilization it was realised that pests harm crops and transmit diseases both to men and animals. Carboaryl designed to kill insects in crops. Meaning of Water Pollution 3. Major Sources 5. Monitoring of the water quality in terms of the standard parameters reveals that the upper stretch (Rishikesh upstream of Kanpur) is the best clean range (D.O. These interactions can be readily explained with reference to a thermally stratified lake. Many radioactive isotopes escape to water reservoirs, rivers and seas from nuclear power reactors. These result from oxidation of FeS2 in pyrite which occurs in large quantities in the underground seams which contain coal. Swages must be treated before it is dis­charged into the water. One way to think about the water cycle is to follow a drop of water around as it moves on its way through the cycle. May 9, 2018 - Explore cherry chai's board "Water pollution" on Pinterest. (g) Thermal pollution of water reduces the D.O. endobj About two thirds of all degradation of water can be attributed to various manufacturing activities, transportation and agriculture. 25-125 ppb; D.D.T. Meaning of Water Pollution 3. Pollution of water is the presence of some foreign organic, inorganic, biological, radiological or physical substances in the water. This is my water pollution poster project that my group members and I put together from Environment 100 that was showcased at the end of the quarter. Thermal pollution is the discharge of hot water into river and estuaries from power stations. This is more true for nitrogenous fertilizers (which are readily soluble) than phosphatic ones. Water Pollution Control and Management. Project Report # 2. These provide nutrition for micro-organisms which decompose the organic matter and consume oxygen and reduce the D.O. The Tamla Nalah delivers a heavy pollution load to the river-phenol (0.02 – 2.0 ppm), NH3 (10-40 ppm), C.O.D. are all centrally collected, treated upto requisite acceptable level and reused for different beneficial purposes. For example, fishes become rare at DO value of 4 to 5 ppm (mg/1). Algal blooms and large amounts of other aquatic weeds causes serious problems. See more ideas about pollution, save earth, air pollution poster. For accurate analysis, it is desir­able to allow a short time interval between sampling and analysis. Project Report # 6. At present there are more than 10,000 different pesticides. The use of chemicals to kill pests dates back to 70 A.D. when arsenic was recommended to kill insects. 6 0 obj Save Water. Project Report # 7. The excessive use of pesticides cause water pollution, by penetrating through soil and getting dissolved in soil water. Impoundments with intermediate nutrient level are called mesotrophic.

The prevention of water pollution from acid mine water is tough challenge for environ­mental chemists. Problems Caused by Water Pollution: This severe water pollution problem caused in the following ways: Sewage waters may contain a number of pathogenic bacteria and viruses. Cadmium and chromium present in sea are toxic for marine animals. Herbicides like monuron, simazin, 2-A-D and 2-4-5-T which are used to clear railroad and highways, weed control in agriculture and forest management are harmful for both plants and animals. Signs 4. impart an unpleasant taste to water. Various types of industrial wastes are continuously poured in streams, rivers and lakes. Historically the first step in water pollution control was the disinfection technique for the prevention of water-borne diseases, which are still in use. Control 12. aromatic chlo­rinated hydrocarbons, etc.) and their addition into water bodies makes it rich in nutrients, especially phosphate and nitrate ions. Water Cycle Poster Project You have been learning about the water cycle. present in the organic debris water is aesthetically unacceptable and unsuitable for bathing, laundering, beverage manufacturing, food pro­cessing etc. Heavy metal ions, if present, will be precipitated as metal sulphides which settle at the sediment layer at the bottom. This ensures that the composition of the sample is identical to that of the water body from which it is collected and the sample shares the same physicochemical characteristic with the sampled water at the time and site of sampling. See more ideas about Pollution, Air pollution, Air pollution poster. stream The stream beds, contaminated with acid mine water, are often coated with odd yellow deposit of amorphous semigelationous Fe(OH)3; H2SO4 of acid mine water destroys aquatic life in water bodies. This project report will help you to learn about: 1. Any pollution of soil of one field need not always affect the soil of neighbouring field. The ex­cessive plant growth presents an unaesthetic scene and disturbs recreational use of water. Effects of Water Pollutants on Different Parameters: Effect of water pollutants on different parameters most commonly associated with water quality are: As the colourless pure water travels through nature, it becomes coloured by various impurities. Di-thio-carbamite group e.g. As already mentioned mercury enter human body through contaminated fishes. The relevant factors for any sampling program are: (f) Data to be collected with each sample, and. >> It is a very impor­tant parameter in management and design of the treatment plants because of its rapidity in determining values.
